how to display data from database using java beans

Question

I need to display the data requested by the user from the database on my jsp page.How can I do it using java beans?

Answer 1

java beans is not a library. It's more like a concept/design pattern for special classes, that hold attributes and provide getter and setter method, which use a naming convention. A quick example:

 private String name;
 private String street;

 public getName() {return name};
 public setName() {this.name = name};

 public getStreet() {return street};
 public setStreet() {this.street = street};

Now we can design a bean that corresponds to a database table. We just use the columnnames as fieldnames and have a java object that represents a table entry.

Have a look at DAO/DTO patterns and ORM (like JPA or hibernate). Those 'implement' this kind of technique and I'm pretty sure, one of those will help.
